Dangerous Music Sum & Minus – Analog Mid-Side Processor

The Dangerous Music S&M gives you unprecedented analog control over the center and sides of your stereo field. By splitting stereo tracks into mid and side components, you can surgically shape mixes and masters in ways that were previously impossible—whether you’re tightening a vocal in the center without losing air on the sides, widening synths, taming cymbals, or adding punch to overheads. Built with Dangerous Music’s no-compromise approach to analog design, the S&M is a powerful creative and corrective tool for mixing and mastering engineers alike.
